Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a retaining wall formwork support. Background Technology

[0002] The construction of retaining walls is a common and crucial basic engineering project in the field of building engineering. Retaining walls are used to support the soil, prevent soil collapse, and ensure the stability and safety of surrounding buildings, roads, and other facilities.

[0003] Traditional retaining wall construction methods face numerous limitations in the application of formwork supports. Currently, existing construction methods often involve custom-made formwork based on the specific dimensions and shape of the retaining wall at each construction site. While this customization approach can meet the precise needs of a single construction site to some extent, it has led to a series of problems. Firstly, custom-made formwork implies high costs; from design and raw material procurement to manufacturing, each step requires substantial investment, significantly reducing profit margins. Secondly, and more importantly, there is the challenge of reusing the formwork. Because the formwork is customized for a specific project, its unique size and structure make it virtually impossible to reuse at other construction sites of different specifications. After a project is completed, these custom-made formworks are mostly left idle or discarded, resulting in a significant waste of resources and contradicting the current advocacy of sustainable development and green building principles.

[0004] With the booming development of the construction industry and the increasing number of engineering projects, retaining wall construction is frequent, creating an urgent need for a new type of retaining wall formwork support that can overcome the drawbacks of customized formwork. This support should be versatile, flexibly adaptable to multiple construction sites with different size and shape requirements, enabling efficient reuse of existing formwork, thereby reducing costs and improving resource utilization.

[0005] In view of the work requirements and existing problems in the above background technology, the inventor has thought about and innovated in this regard, with the aim of providing a retaining wall formwork support for supporting the formwork (8) used during retaining wall construction.

[0006] To solve the above problems and achieve the above objectives, the present invention adopts the following technical solution:

[0007] A retaining wall formwork support for supporting the formwork (8) used during the construction of the retaining wall on the construction face (9), comprising:

[0008] The base (1) is a rectangular structure with at least four anchor nails (11) at the four corners;

[0009] A rotating shaft (2) is connected to a base (1) and can rotate on the base (1);

[0010] The first support link (3) is composed of a triangular support rod consisting of three round rods and a round rod fixedly connected. One end of each of the three round rods of the triangular support rod is fixedly connected to the rotating shaft (2).

[0011] A connector (31) is fixedly connected to the first support rod (3), and the connector (31) has a groove in the middle.

[0012] The second support link (4) has one end connected to the groove in the middle of the connector (31) through a rotating shaft and can rotate on the connector (31), and the other end has a circular hole.

[0013] The extension adjustment rod (5) is nested on the first support link (3) and can move in and out of the first support link (3) and be locked and fixed by the locking bolt (6). There is a groove in the middle of one end of the extension adjustment rod (5).

[0014] The support plate (7) is composed of a rectangular plate and an irregularly shaped connector. The support plate (7) is connected to the groove at one end of the extension adjustment rod (5) by a rotating shaft and can rotate in the groove.

[0015] As a preferred embodiment of the present invention, a first bushing (12) and a second bushing (13) are fixedly connected to the base (1), and the rotating shaft (2) is nested in the first bushing (12) and the second bushing (13) and can rotate in the first bushing (12) and the second bushing (13).

[0016] As a preferred embodiment of the present invention, the base (1) is also fixedly connected with a first adjustment plate (14) and a second adjustment plate (15), and each of the first adjustment plate (14) and the second adjustment plate (15) has a number of first adjustment holes (141) and second adjustment holes (151).

[0017] As a preferred embodiment of this utility model, after the first support link (3) and the second support link (4) are rotated at a certain angle, the second support link (4) is placed between the first adjustment plate (14) and the second adjustment plate (15), and the locking pin (16) is passed through the second adjustment hole (151), the round hole on the second support link (4) and the first adjustment hole (141) in sequence, so that the first support link (3) and the second support link (4) can be locked and fixed.

[0018] The working principle of this utility model mainly includes:

[0019] 1. Base fixing and anchoring:

[0020] The base (1) is a rectangular structure with at least four anchor nails (11) at its four corners. At the construction site, the base (1) is firmly fixed to the ground at the location of the target template (8) by the anchor nails (11), providing a stable support foundation for the entire support.

[0021] 2. Flexible adjustment and stable support of the first and second support links:

[0022] The triangular support rod of the first support link (3) is fixedly connected to the rotating shaft (2). The rotating shaft (2) is nested in the first bushing (12) and the second bushing (13) on the base (1), and can rotate in the first bushing (12) and the second bushing (13), and drive the first support link (3) to rotate.

[0023] One end of the second support link (4) is connected to the connector (31) of the first support link (3) via a rotating shaft, and can rotate on the connector (31), further increasing the freedom and flexibility of the support.

[0024] After the first support link (3) and the second support link (4) are adjusted according to the construction requirements, the second support link (4) is placed between the first adjustment plate (14) and the second adjustment plate (15), and the locking pin (16) is passed through the second adjustment hole (151), the round hole on the second support link, and the first adjustment hole (141) in sequence, so that the first support link (3) and the second support link (4) can be locked and fixed.

[0025] At this time, the base (1), the first support link (3), and the second support link (4) form a stable triangular support structure to ensure the stability of the support structure.

[0026] 3. The support plate can be extended, adjusted, and flexibly adapted:

[0027] The extension adjustment rod (5) is nested on the first support link (3), allowing it to extend and retract, and is locked in place by the locking bolt (6). This design allows the height of the support to be adjusted according to construction needs.

[0028] The support plate (7) is composed of a rectangular plate and an irregularly shaped connector, and is connected to a groove at one end of the extension adjustment rod (5) via a pivot, and can rotate within the groove. The support plate (7) is used to directly support the template (8) used during the construction of the retaining wall. After the rotation angle of the first support link (3) and the second support link (4) is adjusted, the rotatable characteristic of the support plate (7) allows the support plate (7) and the template (8) to remain parallel and provide stable support.

[0029] The beneficial effects of this utility model are:

[0030] 1. This utility model significantly reduces construction costs, improves resource utilization, and reduces waste:

[0031] Traditional retaining wall construction often requires custom-made formwork for each specific project, resulting in high design, raw material procurement, and manufacturing costs. This invention, however, eliminates the need for custom-made formwork for each project, significantly reducing construction costs. Customized formwork is often difficult to reuse after project completion, leading to substantial resource waste. This invention, however, can adapt to the construction needs of retaining walls of different sizes and shapes, achieving efficient reuse of formwork. This not only reduces resource waste but also aligns with the concepts of sustainable development and green building.

[0032] 2. This utility model enhances construction efficiency and flexibility:

[0033] Traditional formwork support methods often require a significant amount of time for installation and adjustment, while this patented support system can quickly adapt to different construction needs through simple rotation, extension, and locking operations. This not only improves construction efficiency but also enhances construction flexibility, enabling construction teams to respond more quickly to various emergencies. Attached Figure Description

[0041] To make the purpose, technical solution and advantages of this utility model patent clearer, the present utility model patent will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model patent. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of this utility model patent.

[0042] Example 1

[0043] In this embodiment, all required components are prefabricated in the factory and manufactured according to specifications. Figure 6 The assembly is completed as shown, ensuring that all rotating parts rotate smoothly. Several sets of this retaining wall formwork support are then fabricated for construction use.

[0044] like Figure 1 — Figure 6 The formwork support shown is used to support the formwork 8 used during the construction of the retaining wall on the construction face 9. It includes:

[0045] The base 1 is a rectangular structure with at least four anchor nails 11 at its four corners.

[0046] Rotating shaft 2, which is connected to base 1 and can rotate on base 1;

[0047] The first support link 3 is composed of a triangular support rod consisting of three round rods and a round rod fixedly connected together. One end of each of the three round rods of the triangular support rod is fixedly connected to the rotating shaft 2.

[0048] Connector 31, which is fixedly connected to the first support rod 3, has a groove in the middle;

[0049] The second support link 4 has one end connected to the groove in the middle of the connector 31 through a rotating shaft and can rotate on the connector 31, and the other end has a circular hole.

[0050] An extension adjustment rod 5 is nested on the first support connecting rod 3 and can extend and retract on the first support connecting rod 3. It is locked and fixed by a locking bolt 6. There is a groove in the middle of one end of the extension adjustment rod 5.

[0051] The support plate 7 is composed of a rectangular plate and an irregularly shaped connector. The support plate 7 is connected to the groove at one end of the extension adjustment rod 5 through a rotating shaft and can rotate within the groove.

[0052] As a preferred embodiment of this utility model, a first bushing 12 and a second bushing 13 are fixedly connected to the base 1, and the rotating shaft 2 is nested inside the first bushing 12 and the second bushing 13 and can rotate inside the first bushing 12 and the second bushing 13.

[0053] As a preferred embodiment of this utility model, a first adjusting plate 14 and a second adjusting plate 15 are also fixedly connected to the base 1. Each of the first adjusting plate 14 and the second adjusting plate 15 has several first adjusting holes 141 and second adjusting holes 151.

[0054] As a preferred embodiment of this utility model, after the first support link 3 and the second support link 4 are rotated at a certain angle, the second support link 4 is placed between the first adjustment plate 14 and the second adjustment plate 15. After the locking pin 16 passes through the second adjustment hole 151, the round hole on the second support link 4 and the first adjustment hole 141 in sequence, the first support link 3 and the second support link 4 can be locked and fixed.

[0055] In summary, the specific usage process of this utility model is as follows:

[0056] First, the retaining wall construction surface 9 and the ground in front of it are cleaned, removing debris and loose soil to ensure a level surface so that the base 1 can be placed stably. Based on the retaining wall design drawings, the installation position of the formwork 8 is accurately measured, and the fixing points of the base 1 are marked to ensure accurate subsequent support installation and effective support of the formwork.

[0057] Furthermore, such as Figure 1 As shown, according to the construction drawings, several of these supports are moved to the pre-marked positions, so that the four corners of the base 1 coincide with the marked points. At the four corners of the base 1, four anchor nails 11 are driven into the ground in sequence using tools, ensuring that the anchor nails 11 penetrate into the ground to a sufficient depth, so that the base 1 is firmly fixed to the ground at the position of the target template 8, providing a stable initial support foundation for the entire support system.

[0058] Step 1: Further, such as Figure 2 As shown, loosen the locking bolt 6 and adjust the extension rod 5 according to the required support height for construction. After adjusting it to a suitable position, use the locking bolt 6 to lock and fix the extension rod 5 to ensure that it will not slip or shift.

[0059] Step 2: Further, such as Figure 3As shown, according to the design slope, height and other requirements of the retaining wall, rotate the first support rod 3 and the second support rod 4 to a suitable angle, and then place the end of the second support rod 4 with the round hole between the first adjusting plate 14 and the second adjusting plate 15 on the base 1. Use the locking pin 16 to pass through the second adjusting hole 151, the round hole on the second support rod 4 and the first adjusting hole 141 in sequence to lock and fix the first support rod 3 and the second support rod 4, forming a stable triangular support structure, ensuring that the support structure is stable when bearing the formwork and construction load.

[0060] Step 3: After the initial installation and debugging of the support is completed, move the formwork 8 to the construction position, and splice and assemble it according to the design requirements to ensure that the connection between the formwork 8 is tight and there are no gaps, so as to prevent grout leakage during concrete pouring.

[0061] Step 4: Further, such as Figure 4 As shown, as the angles of the first support link 3 and the second support link 4 change, the support plate 7 is rotated to keep it parallel to the template 8, ensuring that the support plate 7 can fit tightly against the template 8 and provide stable support for the template 8.

[0062] When the support plate 7 and the template 8 cannot fit tightly together, repeat steps 1, 2, and 4 until the support plate 7 and the template 8 fit tightly together, providing stable support for the template 8.

[0063] Furthermore, a comprehensive review of the installed formwork and supports is conducted, checking whether the anchorage of base 1 is secure, whether the connection and fixation of the first support rod 3 and the second support rod 4 are reliable, and whether the splicing of formwork 8 is flat and conforms to the design dimensions. If any problems are found, adjustments and reinforcements are made in a timely manner, and then subsequent procedures such as rebar installation and concrete pouring can be carried out.

[0064] Finally, it should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
